Evening guys.

 

Got a problem with one of my auto's I'm growing. The bitch doesn't want to go in to flower properly.

I'm growing 2 auto's. Both are the same age and same strain. Dutch passion BlackBerry

 

All went well until a couple of weeks ago when I started seeing light coloured leaves on the sick girl.

It looks a bit like magnesium but it can't be that because I have been giving a little extra mag from the start.

 

Can't be light burn because she got it when she was smaller the the other girl. That one looks perfectly fine.

 

She had a slight cal problem before but I fixed that by giving extra cal (canna mono cal)

She has been given the same food as the healthy girl so it can't be a ph issue because the other girl is perfectly fine.

Furthermore she got a much thinner stem than the other one. Even the branches are a lot thinner.

Only thing that could explain it from looking online is a copper deficiency. But I'm not sure of it and haven't got a clue on how to fix it.

 

I included some pictures. The first 2 are from the sick girl. The last is from the healthy one.

 

Currently feeding them 2ml/L Canna a&b + a bit of cal and some fulvic acid to bring total ec to 1.2 (0.1 background)

Any advise on this anybody?

cheers

These are in coco duke. Can't really see the roots. But she's still feeding. Runoff is about 0.8

Foliar feed with what mate?

Maybe it's a random genetic freak, which didn't pick up a proper copy of the autoflowering gene or something?

i foliar feed regular veg nutes at full strength when needed as it covers all nutrient bases and bypasses the roots entirely you can ph it as normal but im told there is no need but i do it as a matter of course i do a foliar and skip feeding at the roots just to be on the safe side but it is hard to overfeed foliar a tiny drop of washing up liquid and sprayer on fine mist setting soak the leaves underside mostly but all over is good if it colours up then on new growth start root feed again and see,peace

No I did not overdo it with the cal @GoodBudgie. Around 0.1 ec so not very hot.

Could be genetics... its a new strain after all.

I'll drop the cal and keep her alive on 24/0 till the other one is done.

Then switch her to 12/12. Maybe it will get her going then.

 

Thanks for the replies all.
